Inspect and explain conversations in the local Deep Agents Code SQLite session store. Use to look up the current thread's title or name, as a fallback when LangSmith trace tooling is unavailable, for offline or untraced sessions, or when asked to identify or summarize a local dcode thread, inspect checkpoint metadata, list recent local threads, or parse $DEEPAGENTS\_HOME/.state/sessions.db and a thread UUID or prefix.

## From README

Deep Agents Thread Inspector For conversation inspection, prefer LangSmith tooling when available for a traced thread. For saved thread titles, use the local store. Use scripts/inspectsessions.py instead of manually decoding database blobs. It opens the database read-only and deserializes the root message channel with LangGraph's strict MsgPack loader — reading the materialized messages from the latest checkpoint, or replaying writes in checkpoint order when that fast path is unavailable — and emits JSON. Look up the current thread's title Call getcurrentthreadid to identify this conversation, then run the script with that ID and --mode summary as shown below. Read thread.threadname: it contains the saved title, including manual renames, with a fallback to the latest root checkpoint's name for older stores. If it is null, report that the thread has no saved title.
